HERMAN A, SMITH, 03F FLORENCE, $0'UTH PLOW. Q T i it GABOLIISTAL Application filed April. 19, 1923. Serial No. 633,101. r A i i To all whom it may concern:

' Be it known that I, I'IERMAN A. SMITH, a citizen of the United States of America, residing at Florence, in the county of Florence and State of South Carolina, have invented certain new and useful Improvements in Plows, of which the following is a specification.

My invention relates to plows and more particularly to the class of plows usually referred to as rapid set sweep stock plows.

An obj ect of my invention is the construction of a plow having efficient and rapidly acting means of adjusting the position of the sweep which may be operated either while the plow is in use or not in use.

A further object of my invention is the construction of means for controlling the angle at which the sweep is set, which means has the additional advantage of strengthening the plow beam.

A still further object is the construction of a slide, slide rest, and of a locking means to be used therewith.

With these and further objects in view, an embodiment of my invention is disclosed in the accompanying illustration in which Figure 1 is a perspective of my improved plow;

Figure 2 is a side elevation of the plow with the handles and a part of the beam and some minor parts omitted or broken away;

Figure3 is a section on line 3-3 of Figure 2;

Figure 4 ure 2;

Figure 5 is a side view of a fragment of the slide and connecting parts with a part broken away;

Figure 6 is an end view of Figure 5;

Figure 7 is a top plan view of the slide and slide rests;

Figure 8 is a top plan view of the slide;

Figure 9 is a side elevation of the handle for the latch and of the ratchet connected to said handle;

Figure 10 is a section on line 1010 of Figure 9;

Figure 11 is a section of line 11'11 of Figure 9;

Figure 12 is an end elevation of the device shown in Figure 9;

My plow has the usual beam 1 with handles 2. The handles are attached to the is a section on line k t of Fignow be described.

beam by any suitable means such as clips 3 and bolts 4 passing through the clips and handles. The handles are Supported in the desired position by braces 5, one end of which 'is fastened to the beam by bolt 6 and the other end to the handle by bolts '7.

In orderto adjust the position of the handles a slot 8 may be made in each brace. The beam-has the usual clevis 9. -'Attached to the curved end of the beam are two slide rests 10 the attaching means being a rivet or bolt 11. The front ends of these slides are attached to standards 12 by means of bolt 13 allowing pivotal action of said standards. On these standards is bolted the sweep 14 by means of bolt 15 passing through the space between the standards. Means of varying the angle of the sweep to the plane of the slide rests will At the point indicated by 16 the two standards are bolted together-and also at the points marked 17 and 18. A handle 19 is attached to the standard by means of the last two bolts referred to. On the curved part of the beam is secured a quadrant 20 by bolts or'rivets 21. This quadrant has notches 22 therein with which a ratchet co-operates. This ratchet comprises an operating latch 23 pivoted at 24 to the handle and a pin or pawl 25 connected to the'latch by any suitable means as by astrong wire 26. On the handle are two studs 27 having eyes through which the pawl passes. A spring 28 is attached to the pawl and placedbetween the studs 27 to keep the pawl in a notch of the quadrant when not forcibly withdrawn therefrom against the pressure of the spring. A slide 29 is held against the bottom edge of the slide rests by a bolt 30 and is prevented from turning by a lock piece 31 onev end a of which is dropped into the groove 32 in the top of said slide. This piece is held in position by a bolt 33 extending through the slide rests. Washers 34 may be placed on either side of the lock piece. I

The operation of my plow will be easily understood from the foregoing description. The operator uses the handle on the stand ard and by releasing the ratchet places the standard in the position desired. If he desires to have the plow run deep and to throw a large quantity of earth, he pushes the handle away from him and if he wishes it to run shallow he pulls it toward him, setting it at the angle desired by means of the standard, handle and ratchet co-operatin with the quadrant on the beam. The co traction of the standards enables them to act as a support for the beam, preventing it under any unusual conditions from being straightened out.

Having described my invention, what I claim and wish to protect by Letters Patent is 1. In a plow, a beam, one end of said beam being curved, slide rests attached to the curved end of Said beam, standards pivotall v attached to said slide rests, said standards being placed on either side of said beam to act as a brace therefor, said standards being connected together above and below said beam to act as a brace therefor, a sweep attached to said standards, and

means on said standards co-operating with means on said beam to set said standards at 20 different angles to said beam.

In a plow, a beam, one end of said beam being curved, slide rests attached to one end of said beam, standards having the other ends of said slide rests attached thereto, sweep attached to said standards, a slide attached to the bottom edges of said slide rests, said slide having a groove on the up per side thereof, a locking piece, one end of said piece resting in said groove whereby lateral. movement of said slide is prevented, and means to move said standards.

In testimony whereof I affix my signatare.

HERMAN A. SMITH.
